A new type of ion exchange polymer, bis[(perfluoroalkyl)sulfonyl]imide ionomers (PFSI), were developed by the copolymerization of sodium 3,6-dioxa-Δ7-4-trifluoromethyl perfluorooctyl trifluoromethyl sulfonimide with tetrafluoroethylene (TFE) using an aqueous redox initiation system in an emulsion type polymerization. These polymers have been prepared in various equivalent weights and processed into
一种新的类型的离子交换聚合物的,双[(全氟烷基)磺酰基]酰亚胺离聚物(PFSI)中,通过钠的共聚开发3,6-二氧杂Δ 7使用-4-三氟甲基全氟辛基磺酰亚胺三氟甲基与四氟乙烯(TFE)乳液型聚合中的水性氧化还原引发体系。这些聚合物已经以各种当量重量制备并加工成功能膜。新的离聚物表现出出色的化学和热稳定性。该材料具有很高的电化学应用潜力,特别是作为质子交换膜(PEM)燃料电池中的固体聚合物电解质(SPE)。
